Welfare of broiler chickens [PDF]
Italian Journal of Animal Science, 2009 Broiler chickens have been selected for their rapid growth rate as well as for high carcass yields, with particular regard to the breast, and reared in intensive systems at high stocking density ranging from 30 to 40 kg live weight/m2. These conditions lead to a worsening of the welfare status of birds. In Europe a specific directive for the protection

Response of modern broiler chickens to dietary calcium and phosphorus levels below recommendations
Italian Journal of Animal Science, 2020 This study was carried out to investigate the effects of reduced dietary calcium (Ca) and non-phytate-phosphorus (NPP) levels on performance, carcase yield and bone mineralisation of modern broilers. 11,200 one-day-old chicks (Ross-308) were divided into

The effect of using fruit peel on broiler growth and health [PDF]
Veterinary World, 2023 To ensure the long-term viability of broiler farming, producers must address a number of issues, including rising feed costs, a ban on antibiotic growth promoters, and growing consumer awareness of chemical residues in broiler chicken meat. Fruit peel is

Optimizing Cassava Starch Residue Inclusion in Broiler Diets: Balancing Growth Performance, Liver Health and Gut Microbial Dynamics. [PDF]
Vet Med SciModerate inclusion (20–30%) of cassava starch residue in broiler diets improved gut morphology and reduced E. coli counts with minimal adverse effects, while higher levels impaired growth and liver health. The findings highlight CSR's potential as a partial maize replacement, but caution is needed at elevated inclusion rates.

Dietary effect of probiotics and prebiotics on broiler performance, carcass, and immunity
Poultry Science, 2020 This experiment was carried out to evaluate the effects of dietary addition of probiotics (Protexin) and prebiotics (active MOS, mannan oligosaccharides) on growth performance, carcasses, and antibody titer in broilers. A total number of 360-day-old Ross

Regional differences in recombination hotspots between two chicken populations [PDF]
, 2010 Background Although several genetic linkage maps of the chicken genome have been published, the resolution of these maps is limited and does not allow the precise identification of recombination hotspots. The availability of more than 3.2 million SNPs in
